Oxygen supplier (general discussion)

We were required to check the inspection date on the tanks. 20# tank inspections are good for 12 years IIRC. If it was out of date, we were forbidden to fill it and it was a firing offense if you got caught.

Blue Rino will let me exchange any tank I bring them. Most places here won't refill a 20 pounder unless they can see the date on it. (5 years here)
